Source Transformation Definition: Source transformation is defined as a technique to simplify circuit analysis by converting between equivalent voltage and current sources using Thévenin’s and Norton’s theorems. Voltage to Current Conversion: This conversion involves calculating the current supplied by a ...
According to the concept of the invention, however, this can be achieved if the transformer effecting the resistance transformation is not fed from the voltage drop in the electrolyte but from a source via a regulation circuit for which the absence of current flow in the connections effects the...

An outer capacitor voltage feedback loop is also incorporated to ensure well-regulated sinusoidal load voltage in UPS applications, and indirect regulation of the utility line current in UIS applications. -- The performance of the proposed control scheme is examined for voltage-source inverters with ...
2.1.1Voltage source inverter The Most key component of a DVR isVoltage Source Inverter. Voltage Source Inverter is based on a power electronic converter and can change the direct current (DC) into a sinusoidal current (AC) with desirable amplitude, frequency, and phase angle supplied by the en...
[31]. Again, decoupling terms (ωCF) in the control system compensate the dq-coupling in the plant (GSu+) and the current control is represented by its closedloop transfer functionGi. NoPLLis needed since the transformation angleγis calculated directly by integrating the frequency set-pointf...
Current waveform distortion, due to network impedance between source and nonlinear load, also distorts voltage waveform at the point of common coupling. Harmonics are produced by generators, transformers, nonlinear loads and switched devices. Harmonics are integral multiple of fundamental frequency yet ...
